257,093, now Patent No. 2,244,959, dated June l The presentinventirrelates to frames for `glare shields,v and the present application is a division of my Vco-pending application entitled Glare shield, filed February 18, 1939, Serial No.

257,093, which issued on June 10, 1941, and bears Patent No. 2,244,959.

The invention is particularly .concerned with glare shields such as are customarily used in automobiles 4to protect the eyes of the -driver from unusual glare or bright lights, and refers particularly to a frame for a glare shield, the con structionof which permits ready change of the filter material that is employed, so that the shield may be adapted to suit the particular taste or requirements of any individual. l

It is the object of this invention to provide a glare shield ofsimple and inexpensive construction in which thelter medium may be conveniently removed and replaced in case it becomes damaged or worn, or in case it is desired to change the colox` or other ltering properties ofthe medium. Y

One form of the invention is illustratedin the accompanying drawings and described in detail in the following specification, wherein reference is made to the drawing and furtherobjectsand In the drawing- Fig. 1 is -a front elevation of a glare shield embodying the present invention and illustried as attached to a conventionalsunshade of an auto;

mobile? Fig. 2 is an enlarged sectional view taken along line II--II of Fig. '1, and illustrating the construction which makes possible convenient removal of the filtering medium;

Fig. 3 is an enlarged sectional view of the frame shown in Fig. 2, illustrating a locking means attached thereto; and

Fig. 4 is an enlarged fragmentary view in elevation of the same.

As shown in the accompanying drawing. and as fully described in my co-pending application hereinabove referred to, the glare shield generally4 indicated at l0 is attached to a conventional sunshade Il which is customarily secured :lust above the drivers compartment of yan automobile by means of pivotal supporting brackets indicated at l2. Through the medium of these brackets the sunshade ll may be swung to a horizontal position against the ceiling of the drivers compartment when it is not in use or lowered to the vertical position shown in Fig. 1 when the driver is annoyed by the direct rays of the sun.

4il and. is pivotally connected along the lower edge of the sunshade by means of an adjustable bracket including clips i5 and plates i6 supporting rods 2li which extend into opposite ends of a tube 2i to which the frame I3 of the glareshield is secured. The bracket 'and pivotal support"` which are described in detail in my -co-pendlng application referred to above permit the glare.`

shield to. be swung from the full line position lllusirated in Fig. 1 when it 1s in use to the dotted -Iine position thereinjiilustrated when it is not be used within .the frame, although a non-shatbeing used.

The frame I3 which embraces the filter medium il is secured to the tube 2| as shownv in Fig. 3A by welding, soldering. or any'other' suitable fastening means. Any light ltering medium may terable lter medium is preferred, .and any of several cellulose or plastic base compositions are suitable Vfor this purpose and may be obtained in different colors to suit the requirements of the individual driver.

In order to prori'de a great range in :dite: me diums, Ib have found it desirable to use a very thin substance 'of theA nature of Cellophane,".

which is available in a large variety of colors, and of which more than one thickness may be used'. as well as more than one `color, .so that the user may adapt the glare shield to his own particular 4needs by placing in the frame any color or com- The glare shield comprises a frame I3 em- 55 binations of colors, and any number of thicknesses of the filter medium that he desires.`

In order that the filter medium may readily be changed, I have provided a frame the construction of which is illustrated in Fig. 3, in which the main frame`portion I3 is formed preferably of pressed metal or the like, with a cross section which provides -an inclined surface 24 surrounding the frame opening. A clamping framel 25. also preferably constructed of pressed metal. nts

within the frame i3 and causes the filter medium Il to be gripped around its periphery at the in-v clined surface 24 and tightly stretched across the frame opening. The clamping frame 25 is frictionally held in this position and may be removed for the purpose of removing or replacing the lter medium I4.` Where thin sheets of colored material such as Cellophane" 'are used as a filter medium, more than one sheet may readily be placed in the frame constructed in the manner just described. so that it is possible to increase the thickness, t0 combine colors, or otherwise to vary the filtering properties of the glare shield.

Ordinarily the frictional contact between the frame I3v and the clamping frame 25 will suiiice to retain these frames against separation. Inorder positively to prevent. their separation, which might otherwise be caused by the jarring motion A'oi' the automobile or the slippery texture of the 5 filter medium, I have provided a. locking means.

y illustrated in Figs. 3 and 4. AThis locking means vcomprises a' U-shaped locking member 30 mounted on a pin 3l which extends into and is preferably held in one of the grooves of the frame 10 I3 by means of solder or the like. A nger 32 which forms one end ofthe locking member 30 is arranged/co overlap theouter edge of the clamping frame 25 when the locking member is swung to the full line position illustrated in Fig. 15
